Cheers Ill suggest that. Also this has been my main reference as far as the triboelectric effect is concerned. http://en.wikipedia.org/wiki/Triboelectric_effect Iv rubbed a balloon against a cotton t-shirt and then held the balloon against a piece of aluminium foil and the foil stuck. Therefore Id assume that makes the balloon negatively charged right? Would rubbing the balloon with polyester (which is lower down the series) make the balloon positively charged. Im asking as I need to test both positive and negative charges on the antenna. Thanks again in advance.

Cheers guys. Also Iv assumed that if I were to simply drop sand or water over a charged balloon that the sand or water would in turn take on some of the charges on the balloon. Meaning to look at the effect of charged sand when it comes into contact with the antenna I simply drop sand over a charged balloon and then onto the antenna. Is my assumption correct?

Hi Im a student who is doing a project which in part requires the use of the triboelectric effect to charge up dust and then look at the effects of this dust when it comes into contact with a low frequency antenna. I didnt study this at school so all I have to go by is the wikipedia page on the subject, my tutor want to measure the polarity and the amount of charge on a rubber balloon when it is rubbed against various materials (eg wool and polyester.) Does anyone here know how to measure the polarity and/or strength of charge on a triboelectrically charged balloon? Also Iv assumed that simply putting the dust or sand into contact with the charged balloon will in turn charge the sand, is this correct? Thanks in advance for the help!
